I doubt it. I play all of the classes, and I enjoy every role equally. Granted I started out as a healer, and that is what I call myself, this role does not fit my personality. As an INTJ on the Myers-Briggs test, I think being a dps or a tank would fit me better. A healer would definitely be a feeling, sensing person, while I am a thinking, intuitive person. A tank would need to know the mechanics inside and out, as well as know how to balance threat, mitigation and damage dealt. Dps also falls under this umbrella. Do note that this is all my personal observation and not fact.

From the #1 Cata review on Amazon.com: "Blizzard's greatest misstep was blaming players instead of admitting their mistakes.
They've convinced half of the population that the other half are unskilled whiners, causing a permanent rift in the community."

Are you talking about the Meyer-Briggs Personality test, just a general overview of what someone thinks their personality is like versus what their main toon is, or perhaps if they think their character's personality matches their own?

There could be some correlation if we narrowed it down to your "main", but only if we eliminate those who min/max for progression. When classes were more unique (BC... once shaman/paladin were no longer limited to single faction) you could argue "this class/playstyle just fits my personality best". Currently, you could argue that the role you prefer to play is a good indication of your personality.

I chose a warrior, because I enjoyed melee the most in WoW's gameplay(I was enhance shaman and rogue before sticking with warrior). However, looking at how I tend to play in multiplayer shooters, like Battlefield, I most often favor concealment and long range over close quarters. So you'd think hunter or mage would be ideal for me if my personality had anything to do with my class of choice, yet I've had my hunter stuck in level 69 for years and I've never had a mage character I didn't delete pretty soon after creation.
